Manual removal of viruses was more feasable and certainly required at times up until about 4 or 5 years ago. AV software didn't cut it some times and it was possible for some savvy people to manually remove viruses (I used to do it for customers). But times have changed and so have the viruses (read: the people who make them are getting more advanced). They are far more complex and multi-layered then they ever were before. Unless you know what you have, and what variant, it could be impossible to know where to begin.

If the available tools you tried didnt help I wouldn't reccomend popping the hood and gettign your hands dirty. You're just wasting your time.

IF the computer can be saved you can find online communities with virus removal experts that will help you. They use reporting tools and removal tools, but they also know how to use them and more specifically in what order.
